This procedure enables error injection into processor structures based on information
Description:
specified by err_type_info, err_struct_info and err_data_buffer. Each invocation of the
procedure enables a single error to be injected. The procedure supports error injection
for at least one error of each severity type (correctable, recoverable, fatal).
The err_type_info argument specifies details of the error injection operation that is being
requested (see
optional information. The format of err_struct_info is specified for each supported
structure type indicated by the err_struct field in err_type_info. err_data_buffer is optional,
depending on the structure type and whether trigger functionality is used. If
err_data_buffer is not required for the error injection, PAL will not attempt to access the
memory location specified in this parameter.

Description
Index of PAL_MC_ERROR_INJECT within the list of PAL procedures.
Unsigned 64-bit integer specifying the first level error information which identifies the error
structure and corresponding structure hierarchy, and the error severity.
Unsigned 64-bit integer identifying the optional structure specific information that provides
the second level details for the requested error.
Unsigned 64-bit integer specifying the address of the buffer providing additional parameters
for the requested error. The address of this buffer must be 8-byte aligned.
Description
Return status of the PAL_MC_ERROR_INJECT procedure.
64-bit vector specifying the supported error injection capabilities for the input argument
combination of struct_hier, err_struct and err_sev fields in err_type_info.
64-bit vector specifying the architectural resources that are used by the procedure.

Description
Call completed without error
Unimplemented procedure
Invalid argument
Call completed with error
Call completed with error; the requested error could not be injected due to failure in locating
the target location in the specified structure.
Argument was valid, but requested error injection capability is not supported.
Call requires PAL memory buffer
